Embodiment 1

[0012] A modified phenolic antirust paint, the composition of which is expressed in parts by mass: 9.5 parts of high molecular weight polyvinyl butyral; 5 parts of lead chrome yellow; 1.5 parts of zinc phosphate; 0.8 parts of iron oxide red; No. 200 72 parts of paint solvent oil; 1.5 parts of phosphoric acid; 1.2 parts of ethanol, obtained by mixing, stirring, dissolving and filtering each component.

[0013] The product dries quickly. It dries to the surface in 4 hours at room temperature, and forms a film after 24 hours. The thickness of the film is about 20um, and it has a weather resistance of 6 months.

Embodiment 2

[0015] A modified phenolic antirust paint, the composition of which is expressed in parts by mass: 12 parts of high molecular weight polyvinyl butyral; 6 parts of lead chrome yellow; 2 parts of zinc phosphate; 1 part of iron oxide red; No. 200 80 parts of paint solvent oil; 2 parts of phosphoric acid; 1.5 parts of ethanol, obtained by mixing, stirring, dissolving and filtering each component.

[0016] The product dries quickly. It dries to the surface in 3.8 hours at room temperature, and forms a film after 23.5 hours. The thickness of the film is about 20um, and it has a weather resistance of 6.5 months.

Embodiment 3

[0018] A modified phenolic antirust paint, its composition expressed in parts by mass: its composition expressed in parts by mass: 10 parts of high molecular weight polyvinyl butyral; 5.4 parts of lead chrome yellow; zinc phosphate 1.6 parts; 0.92 parts of iron oxide red; 76 parts of No. 200 paint solvent naphtha; 1.6 parts of phosphoric acid;

[0019] The product dries quickly. It dries to the surface at room temperature for 3.4 hours, and forms a film after 23 hours. The thickness of the film is about 20um, and it has a weather resistance of 7.5 months.

Abstract

The invention discloses modified phenolic anti-rust paint which comprises components in parts by mass as follows: 9.5-12 parts of high-molecular-weight polyvinyl butyral, 5-6 parts of lead chromate yellow, 1.5-2 parts of zinc phosphate, 0.8-1 part of iron oxide red, 72-80 parts of No. 200 paint solvent oil, 1.5-2 parts of phosphoric acid and 1.2-1.5 parts of ethanol. The components are mixed, stirred, dissolved and filtered to obtain the modified phenolic anti-rust paint. A product is dried faster, is subjected to surface dry at the room temperature for 3-4 h and is self-dried into a film after 22-24 h; the raw materials are easy to obtain, the production is simple, and the cost is low; the film-forming thickness is 20 mu m, and the weather resistance ranges from 6 months to 8 months; and the anti-rust effect of the product is good, and the modified phenolic anti-rust paint can be widely produced to replace the conventional materials continuously.

Description

technical field [0001] The invention belongs to the field of antirust materials, in particular to a modified phenolic antirust paint. Background technique [0002] Antirust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea water, etc. It is mainly divided into two categories: physical and chemical antirust paints. The former relies on the proper coordination of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc. The latter relies on the chemical anti-rust effect of anti-rust pigments, such as red lead, zinc yellow anti-rust paint, etc., which are used for the anti-rust of metals such as bridges, ships, and pipelines. With the development of industry and the advancement of mechanical technology, it is very necessary to design a primer with strong adhesion, strong weather resistance and low price to mee...
